Can IC bulbs be replaced by CF?

    I was thinking that it would be interesting if the government put a ban or something on IC bulbs for domestic residential uses. It seems like CF bulbs are more efficient and in the end actually more economical (based on $/hours usable before failing). It seems like it would be an easy calculation to determine how much electricity could be saved for the switch-over since you would expect roughly the same # of bulbs to go out each year and be re-purchased.

    What are the pitfalls of CF that might not make this possible? Have i asked this before? Should i be president?

    Interesting leap:

    Compact fluorescents are very efficient.

    --> The federal government should criminalize incandescence. An additional $15 billion for enforcement, tacked on to a military appropriations bill.

    Q: How many web-surfing environmentalists does it take to change a lightbulb?

    Yes, we have had this discussion before, but I'm a big fan of CF lamps.....

    Right now, their low sales are strictly a matter of economics - people don't realize how much money they lose in the long term by not putting up the extra ~$5 up front for the bulbs. Its a classic business problem that plagues my industry as well. Incentives (or putative legislation) would certainly help and I think it is something that should be done.

    Their numbers are much too conservative, though - a good 23 watt, not a 32 watt, CF is equivalent to a 100w incadescent. They also don't include the effect it has on air conditioning in the summer.

    More numbers: a $6, 10,000 hour 23w CF will cost about $30 to power over its lifetime (at $.13per kWh).
    3.3, $2, 3000 hour (total cost: $6.6) 100w incandescents will cost about $130 to power.
